Application filed October 11, 1894. Serial No. 525,648. No model. 4

To all 71 7101)), 1'1 11mg concern:

Be it known that I, Lmvnnxcn i Unna- NUS, of Chicago, in the county of Cook and State of Illinois, have invented a new and Improved Type-\Vriting Machine, of which the folowing is a full, clear, and exact description.

The object of this invention is to provide a superior type-writer having the revoluble type-wheel,on which type-heads are mount ed, and means by which the type-heads may be moved to effect an impression.

Another object of my invention is to pro duce a machine having a simple and efficient feed mechanism to move the carriage backward and forward, also to arrange the key mechanism so thatthemachine may be opcratedto shift from upper to lower case and made to make the line and letter spaces with. great facility and nicety, and, in general, toproduce a machine which is adapted to operate with the utmost speed and do the best work.

Still another object of my invention is to produce a nriable-spacing mechanism for the machine, so that absolutely exact printing may be done, the mechanism being arranged so that a small space may be made for a period or other punetuation-mark, a larger one fora letter, and a still larger one for a combination of letters.

To these ends my invention consists of certain features of construction and combina tions of parts which will be hereiuafterdescribed and claimed.

Reference is to behad to the accompanying; d rawings, formine'a part of this speciiicat ion, in which similar figures of reference indicate corresponding parts in all the views.

Figure l is a plan view of the machine cmbodying my invention. Fig. 2 is a longitudinal section on the line 2 2 of Fig. 1. Fig. 3 isa cross-section on the line 3 il'of Fig. 2, looking toward the carriage. Fig. 4 is a detail sectiononthelineet i of Fig. 3 and illustrates an end elevation'of the carriage. Fig. 5 is a broken detail plan of the revoluble disk or plate, the type mechanism thereon, and the keys which operate the type. Fig. Gisaerosssection on the lineG ii of Fig. 2.

frame it), which supportsa vertical post 11,

and on this is' a revoluble hollow shaft 12,

journaled in ball-bearings 13-a-t'the top and bottom, and the shaft carries a revoluble disk or plate 14, which, together with the printing mechanism thereon, is inclosed by a dishshaped cover l5,which is fastened by a thumbscrew 16, or equivalent device, the post 11. On the periphery of the typedisk 14 are rings 17 and 18, arranged one beneath the other and, connected by a circumferential band 1.), (see Figs. (land 7,) which is cut away at regular intervals to provide openings 20 for'the type-heads 22, which are carried on vertical spindles 23, held looselyin holes'flt in the rings 17 and 18. The typeheads 22 have central grooves, as shown in Fig. 3, thusdividing the heads into twoparts,

the upper of which preferably carries the lower-ease type 22 and the lower part "carries the upper-case type 22; but of course this arrangement may be reversed. It will be observed that the wheel may be very c onveniently madeof sufficientwidth to permit the combination of .type letters or logotypes It will be understood that in either case each of the wheel parts carries a character.

As the disk 1% revolves it brings the typeto the top: of

head 2'3 opposite an inking-roller 25, which is v journaled on an arm 26, extending from the post 11, and immediately after leaving the roller the type on the wheel is turned so as to press against the roller-platen 27, which is of the usual kind. and is carried by a movable carriage, as hereinafter described, the roller being held horizontally opposite the face of the printing mechanism, as shown clearly in 2. The spindles of the type-wheels are each provided with pinions 28, which,

presently.

when the spindles are raised, engage a rack 39 on a suitable support 30, (see Figs. (5 and 7,) the rack being preferably concentric with the shaft 12, and thus the movement of the disk 1d causes the pinion to roll on the stationary rack and so turn the type-head and bring the type thereon first against the inking-roller and then in position to print on the platen 27. This obviates the use of an ink-ribbon and enables the type to be perfectly inked just before it prints. Under normal conditions, however, the type-heads turn below the inking-roller and platen and only the type-head which is to print is inked, and consequently a'great saving of ink is effected. r

The upper end of the arm 26 extends outward above the spindles and is bent to form a cam. 31, as shown in Figs. 2 and 6, which cam is placed just beyond the printing-point, so that after a typehead has printed the spindle :33 strikesagainst the cam 31, and is thus forced downward to normal position, thus nntking it impossible for any type-wheel to stick up and cause a bad impression. The disk 14 and the type-heads are kept in constant and rapid rotation, this being effected by means of a pulley 9 on the shaft 12, and a belt 8, which is adapted to connect with a spring, electric, or other motor.

The several--type-heads are thrown up to place by the mechanism described below. For each type-spindle 28 there is a type-lever 32, (see Fig. 2,) which is journaled in a hanger 33, placed radially on the under side of the disk 14, and the lever has at its outer end an arm 34, adapted to swing upward and lift the spindle 23, and at its inner end a depending arm 35, which is adapted to strike the reducer] upper end 36 of a type-bar 37, which is verticall y movable, and there is atypc-bar for each lcverand a key foreach type-bar, as described The reduced ends of the type-bars move vertically through apertures 38 in a guide-plate 39, which is shown best in Figs. 2 and 5, and in order that each type-har may strike its appropriate type-lever the several type-bars are arran god so that no two of them alinc,th at is,they are arranged at d ifferent dis tances from t he center of the type-disk 14, and the typc-levers 32 are of dissimilar lengths, so that their arms 35'are arranged in a spiral line, as shown clearly in Fig. 5, and thus itis possible for each arm 35 'to strikeits appropriate typebar when the latter is raised, without coming in contact with any other type-bar.-

'lhe type-bars 37 are each pivoted to a key 40, which is arranged horizontally in the mar chine-frame in the usual way, being ful-' crumcd as shown at 42. and provided with a finger-piece 41 ,and the finger-pieces of the several keys are arranged in banks after the usual manner. The type-bars 37 move through a plate 43, as shown clearly in Fig. 11, and beneath this plate on each type-bar is a spring 44, which carries back the key and typeba'r after the latter has been raised.

On the under side of the guide-plate 39 is a slide-plate 46, which is held to the guide-plate 47 in the slide-plate, (see Fig. 5,) and the slideplate is also provided with slots 4.5 wide enough to permit the passage of the body portion of the type-bars through them. The

and upper case printing, that is to say, if the slide-plate is pulled forward a type-bar may project bodily through a slot 45, and the upper end 36 of the type-bar, striking an arm 35 of a type-lever 32, will move the lever ciently to cause its arm 34.- to raise the typehead 22 so that the lower portion of the head will come opposite the platen 27 and thus print an uppercase character, but in normal position the slidoplate 46 is pushed back position shown in Fig. ll, and this bringsthe slide-plate into position to strike the shoulder oi the type-bar 37 and prevent the latter from moving upward through the slot of the shift the slideplate.

The platen 27 is carried by a carriage 5- which is movable back and forth opposite one edge of the printing-disk and its mechanism,

porting-rod a d at the other has rollers 56, which clasp a gun ieway 57. (See Fig. 2.) The platen is journaled in brackets 58, which are scour-rd to thdarms 59 of the carriage, these when desired the platen, the feed-roller beneath it, and the papor-guidcsabove and below it may be thrown back so as to permit the work and the printing mechanism to be examined.

6] ,which is and a paper-guide held just beneath the platen 27, 62 extends inward from the,

rollers, and above the platen is another paperguide U3,which is upward from the arms 5.).

The platen 27 isprovided with the usual end-milled wheels (35 to enable it to be turned by hand, and it has the customary ratchetturning.

The carriage 5. is moved backward and forward by means of a tape or belt G8,,which e20. tends longitudinally beneath it and to which end secured to a spring-barrel oil, the spring '70 of which is coiled. within it and is secured at one end to the barrel and at the other to the shaft 71, which carries the barrel, this by means of screws 4.8,projccting through slots slide plate is to adjust the type-bars forlower 7 5 sufiito the slide-plate, and hence when the end 36 of the The slideplate 4G 5 53, which may be struck to tiltt-he lever and and the carriage at one side slides on a suparmsbeing fulqrumed, as shown at (it), so that no The arms 5!) carry a feed-roller n5 carriage back to a point opposite the meeting held on arms 64, extending 12o wheel 06 and pawl G7 to prcvcntits accidental the carriage is attached, this belt being at one I30 shown in Fig. 3, and this shaft being journaled in suitable supports 72 and provided with a ratchet-wheel 7 3 and pawl 7et to prei'ent it from turning in the Wrong direction. The shaft is provided at one end with a disk 75, having pins 76 thereon, the disk and pins thus serving as the key by which the shaft may be turned so as to tighten the'spring and regulateits tension. The opposite end of the belt 68 is secured to a pulley 77 on a shaft 78,which is parallel with the shaft 71 but at the opposite side of the machine, as shown clearly in Fig. 3, and the pulley 77 is loosely mounted on its shaft 78 and is normally held to rotate therewith by means of a clutch 7U, keyed to slide on the shaft in the usual manner. A'spring backs'the clutch and normally keeps it in engagement with the pulley. 1n orderto prevent the shaft 78 and the pulley 77 (as long as it is coupled thereto by the clutch 79) from rotating in the direction in which the spring '70 tends to turn them, I provide a pawl 80, which engages a ratchet-Wheel 81, mounted to .turn with the shaft 78. The ratchet-wheel S1 is also engaged bya rack 82, (see Fig. 3,) which is movable vertically opposite the ratchet-wheehand the said rack slides in a guide 83 and is pulled upward by a spring 84.

The lower end of the rack-bar 82 is pivoted to a lever 85, which swings vertically, as lever is engaged by one end of the spacing-key 86, which extends forward to the keyboard and is provided with a finger-piece 87, extending the full width of the keyboard, the opposite end of the said finger-piece being pivoted to a lever 88, the pivot 89 of which is opposite the corresponding pivot of the spacing-key S6. The lever 88 and spacing-key 86 are connected by a cross-piece 90, (see Fig. 2,) which is arranged in the usual manner beneath'the keys 40, and thus whenever a key 40 is depressed to print a letter, as already described, the lever is raised, thereby depressing the rack-bar 82, so that the ratchet-wheel 81' and with it the shaft 78,'the cluch 70, and the pulley 77 will be turned against the tension of the spring 70, causing the said pulley 77 to pull on the belt 68 and move the carriage 5t and the platen a distance of one letter-space and at the same time partly winding up the spring 70. 'hen the letter is printed and the key returns to its normal posit-ion, the spring 84 will restore the rack 82 to its upper or normal position, the pawl 80 preventing the return movement of the It will be seen that the effect is the same whether one of the letter-keys or the spacingkey b6 is depressed.

To provide for variable spacing, that is, to make, a space corresponding to the character printed, the several keys 40 are provided with notches 40" on the under side, these being relatively shallow or deep, according as the space to be made large or small. Consequently when a key with a small notch or perhaps with no notch is depressed it will pulley 77 and the carriage move'tlle cross-piece a comparatively long distance and thus make a large space, while one of the keys which is more deeply notched will move the'crosspiece a less distance and therefore make a smaller-space. It will be obvious that the notches may be provided in the cross-piece 90, as shown at 90 in Fig. 12, the keysin that case having no notches.

When the carriage has been moved from left to right to print a line, all that is necessary toreturn itis to release the clutch 79, and the tension of the spring 70 turns the spring-barrel (39 and pulls on the belt 68, so as to pull back the carriage and unwind the belt from the pulley 77. This releasing of the clutch is effected by the following mechanism: The clutch is connected by means of the usual groove and pin, as shown in Fig. 1, or in any equivalent manner, with a lever 91, which is fuleruined near itscenter, as indieated at 92, and the free end of the lever has a pin 93, which engages a cam-tooth 9-1 onthe return-key 95, terminatingat its front end in a fingerpiece 96, arranged on the keyboard with the other linger-pieces, and the returnkey is fulerumed on the same pivot 42 as the other keys. It will be seen then that by simply depressing the finger-piece 9.6 the rear end of the carriage-return key is raised, moving the cam-tooth 94 againstthe pin 93 and swinging the lever Jl so as to move the clutch 79 out of engagt-unent with the pulley 77 against the tension of the spring 80, thus releasing the pulley 77 and permitting the return of the carriage.

Each time the carriage is moved to the left by the depression of one of the keys -lO the rack 82, by turning the pulley 77, partly re winds the spring 70, so that when the carriage reaches its extreme position to the left the spring is fully rewound. The winding of the spring therefore is entirely automatic.

In order that the spring may be wound up when the carriage is moved to the left by hand, the carriage is provided with a rackbar Sl, which is secured to its under side and engages the ratchet-wheel 81, so that when the machine is being used in the ordinary way the rack has function; but if the carriage is pushed to the left the rack-bar engages the ratchet-wheel and turns the shaft 78 and pulls on the belt (38, so as towind up the spring 70 of the spring-barrel, and the carriage may therefore be returned, as described. i

The arrangement above described provides for making the letter-spaces, and to make the necessary line-spaces the mechanism shown best in Fig. 10 is employed, which does the line-spacing automatically on the return of the carriage. I

The shaft of the platen 27 is provided with a spiral slot 97, which is adapted to engage the pins 98 of the short shaft 99, which is journaled on the frame 10 opposite the end of the platen-shaft, and the shaft 99 is provided with a ratchet-wheel 100, which is engaged by a pawl 101, this locking the shaft so that it can turn in but one direction. As a result, when the carriage returns to begin a new line the pins 98 enter the slot U7 and, acting on the walls of the slot, turn up the platen, so as to bring the paper into position fora newline; but when the platen begins to move away in the opposite direction, while a new line is being printed, it is not turned, because the ratchet-wheel 100 and pawl 101 permit the slotted shaft of the platen to turn the shaft 9!).

From the foregoing description it will be seen that the machine can be easily and. perfectly controlled and that the keys merely serve to throw the type into position for printing, while the actual work is done by a rotating disk or cylinder, and hence the letters are all similarly and nicely printed.

Having thus described my in vcnlion, I claim as new and desire to secure by Letters latent 1.
